The brachial plexus arises from the lower cervical and upper thoracic spinal nerve roots. It courses between the anterior and middle scalene muscles and adjacent to the subclavian artery. The brachial plexus may be visualized by both MRI and CT. Symptoms of a brachial plexopathy commonly are nonlocalizing. Traumatic injuries and involvement by tumors probably account for the majority of etiologies responsible for these plexopathies. Inflammatory processes also involve the brachial plexus. This article reviews the anatomy of the brachial plexus from both surgical and radiographic approaches and also addresses the symptomatology of brachial plexopathy underlying it.

UI	MeSH Term	Description	Entries
D007249	Inflammation	A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.

D010523	Peripheral Nervous System Diseases	Diseases of the peripheral nerves external to the brain and spinal cord, which includes diseases of the nerve roots, ganglia, plexi, autonomic nerves, sensory nerves, and motor nerves.

D001917	Brachial Plexus	The large network of nerve fibers which distributes the innervation of the upper extremity. The brachial plexus extends from the neck into the axilla. In humans, the nerves of the plexus usually originate from the lower cervical and the first thoracic spinal cord segments (C5-C8 and T1), but variations are not uncommon.	Plexus, Brachial
D003952	Diagnostic Imaging	Any visual display of structural or functional patterns of organs or tissues for diagnostic evaluation. It includes measuring physiologic and metabolic responses to physical and chemical stimuli, as well as ultramicroscopy.	Imaging, Diagnostic,Imaging, Medical,Medical Imaging
